As a media baby I've been exposed to the faces of thousands of actors and actresses over the eons in addition to the usual traffic of faces from Mundania. I suspect your neural casting-director subroutine goes through the same sorting process that mine does when looking for the right face to present the right concept. Said subroutine is also open to résumés from certain astral personages who may want a word with you, or who are sending you a heads-up in re future cast members to appear in your "real life".
